Betaseed hybrids productivity under the Lipetsk region conditions

The purpose of research is to study sugar beet hybrids of the modern selection of the Betaseed company, which are able to maintain high yields and good quality of the raw materials obtained in the soil and climatic conditions of the Lipetsk Region. Comparative characteristics of ten hybrids (BTS 320, BTS 845, BTS 915, BTS 591, BTS 980, BTS 960, BTS 705, BTS 1965, BTS 950, BTS 7160) of Betaseed sugar beet cultivated in the Lipetsk Region are given. The economic value of hybrids was determined by their productivity in comparison with the best production hybrids. All studied hybrids of the Betaseed company in the conditions of the Lipetsk Region showed a very high yield, on average for hybrids it was 66.3 t/ha. Among them, two hybrids with higher productivity stood out - these are BTS 320 (70.5 t/ha) and BTS 950 (70.2 t/ha). In comparison with the control variant of Recordin, which is one of the best hybrids of European selection, the excess productivity was 6.9-6.6 t/ha (10.8-10.4 %). The lowest productivity (62.9 t/ha) was obtained when cultivating the BTS 845 hybrid. The best Betaseed hybrid in terms of biological sugar yield was BTS 320, which provided a sweet product yield of 12.76 t/ha and formed roots with a sugar content of 18.10 %. The second best hybrid was BTS 950, which was slightly inferior in yield and sugar yield to BTS 320. All hybrids of the American company Betaseed had a significantly higher sugar yield than the Recordin hybrid, the difference varied widely - from 0.49 to 2.16 tons /ha, on average, for all ten hybrids, the excess was 1.41 t/ha (13.3 %).
